Abstract
There is disclosed a method of programming a flash memory cell, which is performed applying a given voltage a gate and a drain and maintaining a source and a substrate at a ground potential. The method variably applies a given voltage, with two or more steps, to one of the gate and drain terminals while applying a given voltage to the other of the gate and drain terminals, thus reducing the programming current per cell. Accordingly, the present invention can improve reliability and throughput of the flash memory cell.
